CVE-2025-68232

In CVE-2025-68232, a race in the Linux kernel veth TX path (veth_xmit()) could permanently stall the TXQ on ARM64 (Ampere Altra Max) due to an incorrect __ptr_ring_empty() check from the producer side, causing a lost wakeup. The fix unconditionally flushes the peer after netif_tx_stop_queue() and...
